Honda Car Forum

subsequent to a recent thread, there are indeed a batch of defective
honda thermostats out there - i bought one a while back for "preemptive
maintenance" on a 20 year old car and on fitting, the car had classic
warmup problems. replaced again, back to perfect.

moral of the story: don't assume that because your oem honda
[manufactured by n.t.c.] thermostat is new, that it works properly.

hopefully the duds will have worked their way out of the system by now
[i bought it a couple of years ago], and honda will replace under
warranty for a year, but it's a pita if you get one.

Hee hee hee. For Toyota some transmissions come skipping gears. Newer
3.5L V6 have piston slap and others have oil consumption problems (1
qt/600 miles). You're right. Always check and double check, don't
assume.

Soak in hot water 1st, see if it opens.

Don't some of the high pressue systems open at temps above boiling?

The RMS Titanic sank on April 15th. US income taxes
are due on April 15th. Coincidence? I think not.

I never heard of, engine must be too hot if thermostat opens
this late. F20A's spec says opens @78±2ºC, fully by 90ºC.

A system under pressure can be at temperatures well above 100 DEG C
without boiling.

Have you never heard of somebody popping the radiator cap off a system
at temp and having steam expode in their face? It wasn't steam before
the pressure was relieved.

How is this relevant to testing a *thermostat ? Which * opens @
>100ºC ?

Most Honda thermostats /start/ opening at 78C, and are /fully open/ at 90C.

A pressurized cooling system can sustain up to about 115C before boiling.
